I have a set of 7-sp only, 1989 Chorus, I think, and a set that has the little lever on the side. I also have 2 blue inserts and 1 yellow insert.
What I don't have, is a set of instructions on how to mount them. I've mounted them two different ways so far, and can't get an index "click." They just swivel.
The Chorus has a matching RD/FD/Regina America freewheel, and I'd like to mount them right, as a 7-speed.
The other set, which has the little lever on the side, I'd like to mount as a 6-sp.
1-Is there a .pdf out there with the blow-up diagram for these?
2-Which insert is 6, which insert is 7?
3-Can I use the 6-sp with a Shimano 600 freewheel?

3- No, not with indexed levers- the gear spacing is different for campy and shimano, you can use them in friction mode
edit-the table on the link below seems to indicate that these shifters can be used with shimano compatible. unusual for campy

here see if this site helps any:
it appear that yellow is 6 speed and blue is 7 speed based on the table on this site

the previous post reminded me of something. I have my '94 parts/service manual. is shows synchro2 but when I get home tonight I will try and scan the 'exploded' view for you it might help.

Here is the PDF: http://www.yellowjersey.org/photosfromthepast/syncro.jpg
I don't have the instructions here with me, I can scan them tonight for the inserts.

Amazing help, folks, and I have successfully assembled a 7-sp group onto a bike. I have also got the 6/7 done, I think, and taped it in place and put it in a ziploc, for when I install it.
It was pretty much trial and error. I was stuck for a while, thought I had the wrong shifter bosses.
A dowel and a mallet um, helped.
Now, if I can just figure out where the seat post (Campy 2-bolt) and saddle (Body Geometry) went in May, I can finish.
Thanks again, all who assisted. The tables were right on, blue for 7.
Bianchigirll, if you can, that would be great. I got a set of 8-sp in today, for another bike, and though it has fewer parts, I'm not tempting fate with the Trial and Error thing too many times.....
Again, BF proves to be the deal.
